Starting something new can be a scary thing because of all the unknowns. However, anything worth having requires us to begin somewhere. Our desired destiny only comes because of intentional energy put towards uncovering the goal.
Clarify your reasons for beginning. Use each day to seize the opportunities that project you closer to your goals. Make today's efforts SMART (Specific, Measurable, Assignable, Realistic, Time based). Embrace who you are and where you are today; then push for the goals that project you to be better. Be clear about each step you pursue towards change by aligning your actions with your core values.
It's a new day, feel free to improve yourself, gain new friends, get rid of old habits and dysfunctional perspectives. Focus on the areas that matter the most. Start small and work your way up.
